PUMP VALVE.

Application filed July 7,

The present invention relates to improvements in pumps and has reference more particularly to a valve structure for .use in conjunction with deep wells.

One of the important objects of the present invention is to provide a device of the above mentioned character which will facilitate the lifting of water upwardly from a deep well in a comparatively simple and elficient manner.

A further object of the invention is to provide a device of the above mentioned character which is simple in construction, inexpensive, strong and durable and further well adapted to the purpose for which it is designed.

Other objects and advantages of the invention will become apparent during the course of the following description taken in connection with the accompanying drawmg.

In the accompanying drawing forming a part of this application and in which like numerals indicate like parts,

Figure 1 is a side elevation of the device embodying my invention showing the working valve in its uppermost open position, the standing valve being closed.

Figure 2 is a vertical sectional view .through the device showing the working valve in its lowermost position with the same closed, the standing valve being shown open.

Figure 3 is a transverse section taken approximately on line 3'3 of Figure 2 looking in the direction of the arrows, and

Figure 4 is an enlarged detail of the connection between the spool of the standing valve and the slidable rod associated therewith.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1- designates a cylinder, and arranged within the lower end thereof is the standing valve designated generally by the numeral 2. The standing valve comprises a body portion 3 having annular grooves formed thereln to receive the packing rings 4 which engage the inner wall of the cylinder in the manner as clearly shown in Figure 2. A. central outlet opening 5 is formed in the top of the body portion 3 of the standing valve 2, it being understoodof course that the body 3 is hollowa An enlarged inlet opening 6 is provided in the bottom of the body por 1926. Serial No. 120,946.

tion 3 and the same extends around the tubular guide 7 the purpose of which will be hereinafter more fully described. The supporting means for the tubular guide member 7 is shown at 8 with reference more particulariy to Figure 3.

An elongated tube or sleeve 9 has its upper end extending through the tubular guide member 7 and through the outlet 5 formed in the top of the body portion 3. The lower end of this tube or sleeve is closed as illustrated at 10 in Figure 1 of the drawing and adapted to extend downwardly into the well for an appreciable distance. This tube or sleeve 9 is of such diameter as to be free to slide through the head or body portion 3 of the standardvalve 2.

The upper end of the slidable tube or sleeve 9 is flanged as illustrated at 11 and extending from the flanged upper end of this tube is the threaded extension 12.

Adapted to form a valve or closure for the outlet 5 formed in the top of the hollow body 3 isthe spool like member 13, the same having its lower end threaded on the externally threaded extension 12 formed on the upper end of the tube or sleeve 9. A suitable washer 1 1 is interposed between the flange 10 and the bottom of the spool 13 in the manner clearly shown in Figure 4: and this washer seats on the top of the body portion for preventing any leakage of the water at the outlet 5 when the tube 9 and the spool-like valve 13 are in their lowermost positions.

A cage 15 is provided on the top of the body 3 for the valve like spool 13 for the purpose of limiting the upward sliding movement thereof.

The present invention further includes a 1 working valve designated by the numeral 16, the same being disposed within the cylinder 1 above the standing valve 2 which is adapted for reciprocatory movement with in the cylinder in the manner to be presently described. The working valve comprises a hollow body portion 17 which is provided with an outlet opening 18 in the top thereof,

the bottom of the body being open as 1s clearly shown in Figure 2. Suitable packing rings 19 extend circumferentially around the body and are disposed within annular grooves provided therefor in the body. A cage 20 is arranged on the top of the body 17 of the working valve 16 and adapted for operation with the cage .29

the spool 21 which forms a closure valve for the outlet opening 18 formed in the top of the body 17.

An elongated rod is secured at its upper end to the upper spool 21 and this rod ex tends downwardly through a suitable bush ing' 23 provided therefor in the upper central portion of the spool 13, and the lower end of this rod extends downwardlyinto the elongated sleeve or tube 9. head 2 1 is formed on the lower end of the rod and the same is operable within the tube or sleeve 9 and is further ot such diameter as to engage the inner wall of said tube as is clearly shown in Figure 1.

an operat-i rod or shatt extends downwardly '.nto the top of the cylinder 1 and is secured at its lower end to the top of the cage some providesa means whereby the working valve 16 will be reciprocated within the cylinder 1. The upper end oi this red or shaft 2 is adapted to be actu ated by appropriate means (not shown) and which is further well known in the art.

With the partsarranged as shown in Figure 1 of the drawing, the spool 13 is seated on the top of the body 3 ot the standing valve la-thus closing the outlet 5 and preventing any water entering the lower portion of the cylinder. With the spool 21 open or rather disengaged from the top ot the hollow body 17 so that the outlet opening 18 is uncovered, the water which is in the cylinder 1 between the standing; valve and he workiiig valve will be permitted to flow upwardlythroug'h the working valve and the cylinder 1 wheretrom it is discharged out of the spout (not shown).

On the down stroke of the body portion 17, the spool 21 becomes unseated from the outlet opening 1.8 a suiiicient distance to per- Init the upward flow of the water through the working valve. (in the further down ward movement oi" the body portion 17, the top of the cage 20 will engzgage the top of the spool 21 and move the same downwardly simultaneously causing the rod to move downwardly illIUOILQIll the standing valve 2 so that the lower end ot the rod will move downwardly within the tubular sleeve 9.

On the upstroke ot the working valve 1t; thespool will be seated on the top of the head 17 thus closing the outlet opening 18 and when the shai't or rod 25 is moved upwardly in the cylinder 1. a suction will be created in, the lower portion of the cylinder between the staiiding valve and the working valve su i'sci'erit enough to cause the unseatinp; ot' the spool 13 so that the water will rush into the cylinder through the inlet 6 and will enter the chamber between the staiiding valve and the, working valve through the outlet 5 thus forming a column or water in said chamber which column will be ejected out through the working valve when the latter is operated in the manner shown in Figure 1;

ln this manner, water may be lifted upwardly from a deep well in a comparatively simple and eflicient manner and the device will at all times be positive in its operation.

The simplicity in which my improved pump valve is constructed enables the parts to be readily assembled or disassembled, and may furthermore be iiiailutactured at a very low cost.

lVhile l have shown the preferred embodiment oi my inventioii it is to be understood that "nor chaiiges may beinade in the inveutioii without departing from the spirit of the invention arid; the scope of the,

appended claims.

Having thus described the invention; what I claim asnew and desire to secure by Let tors Patent is:''-. 4
